Description

Technical Field

[0001] The present invention relates to the technical field of pressure resistance detection, and particularly relates to a pressure resistance detection device for water meter production with a sliding positioning mechanism. Background Art

[0002] The internal structure of a traditional water meter can be divided into three major parts from the outside to the inside: a housing, a sleeve, and an inner core. The housing is made of cast iron. After water comes out of the water inlet, it passes through the lower annular space of the housing, which is called the "lower ring chamber". Above this annular space is the "upper ring chamber" that communicates with the water outlet. There is a filter screen with small holes at the bottom of the sleeve to filter out impurities in the water. There are two rows of round holes on the side of the sleeve, and the positions of the holes exactly face the upper and lower ring chambers of the housing. Obviously, the lower row is the water inlet hole, and the upper row is the water outlet hole. It is particularly worth noting that these two rows of holes are drilled obliquely along the tangent direction of the circle. Note that the directions of the two rows of holes are opposite. When water flows in along the tangent direction from the lower row of holes, a rotating water flow is bound to be formed, which is very important for the operation of the water meter.

[0003] After the production of the water meter is completed, it needs to be subjected to a pressure resistance test before it can be put on the market. Most of the existing water meter pressure resistance detection devices are directly connected to the water meter connector through a water pipe, and the water pressure in the water pipe is changed to observe the water leakage situation of the water meter. Since there are gaps at the connection itself, the water leakage is relatively obvious. When performing the pressure resistance test later, the tester cannot determine whether it is normal water leakage or water leakage caused by different pressures, resulting in an increase in detection errors and inability to judge normally.

[0004] A pressure resistance detection device for water meter production with a sliding positioning mechanism with a publication number of CN114061709B includes a positioning component and a water delivery mechanism installed on the side of the positioning component. The positioning component includes a pair of clamping heads. Each clamping head includes a connecting sleeve, a pipe head is inserted and matched on the side of the connecting sleeve, and a plurality of return springs are connected between the side of the pipe head and the side of the connecting sleeve. In the present invention, by pushing the two connecting sleeves to move away from each other, the return springs are in a compressed state. The two sides of the water meter are placed between the two connecting sleeves. After releasing the two connecting sleeves, each return spring loses pressure and returns to its original state, driving the two connecting sleeves to move closer to each other in the reverse direction. The two sides of the water meter are clamped and fixed. The water delivery mechanism performs water treatment on the water meter, and judges the pressure resistance of the water meter through the degree of water leakage of the water meter. The positioning function of the water meter is realized through the provided clamping heads, ensuring that the water meter is in a stable state during the detection process and avoiding inaccurate detection results caused by external factors.

[0005] In the prior art, the adjustment of the water meter cannot be achieved quickly, and the corresponding insertion cannot be carried out accurately and quickly, which is not conducive to fully ensuring the stability of the pressure. Therefore, improvements are needed. Summary of the Invention

[0006] The object of the present invention is to solve the drawbacks existing in the prior art, and a pressure resistance detection device for water meter production with a sliding positioning mechanism is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A pressure resistance detection device for water meter production with a sliding positioning mechanism, including a mounting plate. One side of the upper end of the mounting plate is provided with a pressurizing mechanism. Two high-pressure corrugated pipe fittings are connected to the pressurizing mechanism. The front ends of the two high-pressure corrugated pipe fittings are respectively connected with a moving mechanism, and the moving mechanism is installed on the upper end of the mounting plate.

[0009] The front end of the mounting plate is provided with a lifting mechanism. A lifting plate is installed on the lifting mechanism. The other side of the upper end of the lifting plate is provided with a pushing mechanism, and a vertical plate is arranged on the pushing mechanism.

[0010] Two openings are respectively arranged on both sides of the vertical plate. A horizontal shaft member is arranged at the lower end of the opening. The horizontal shaft member is rotatably connected to the vertical plate. A lifting frame is slidably installed in the four openings together. A pressing shaft member is rotatably connected to the lifting frame. The four pressing shaft members are respectively located above the four horizontal shaft members. Both sides of the vertical plate are rotatably connected to a vertical shaft member. The vertical shaft member is arranged between the two pressing shaft members on the same side. An elastic mechanism is arranged at the lower end of the lifting frame, and the elastic mechanism is arranged on the vertical shaft member.

[0011] Compared with the prior art, the present application can quickly clamp and fix the water meter, and at the same time can effectively adjust the position of the water meter, which is convenient for effectively inserting two conical sealing plug pipe fittings into both ends of the water meter respectively. And through the action of the pressurizing mechanism, the pressure inside the water meter can be increased to effectively carry out the pressure resistance detection, and can fully ensure the height and position of the water meter, realize accurate positioning, and can fully ensure the stability of the water meter position during the pressure resistance detection, and improve the accuracy of the detection.

[0012] Preferably, the elastic mechanism includes two moving grooves opened on both sides of the upper end of the vertical shaft member. A sliding rod is fixed in the moving groove. A sliding plate is slidably sleeved on the sliding rod. A spring is sleeved on the sliding rod. The two ends of the spring are respectively fixed to one side wall of the moving groove and the sliding plate inside. The upper end of the sliding plate is rotatably connected to an inclined rod. The upper end of the inclined rod is rotatably connected to the side of the lifting frame away from the vertical plate.

[0013] Furthermore, the operation of the elastic mechanism can effectively control the lifting frame to descend. After contacting the water meter, the position of the lifting frame can be fully fixed, and the pressure on the lifting frame can be continuously increased to fully ensure the clamping force on the water meter. That is, during operation, as the vertical plate moves, the position of the sliding plate can be fixed through the action of the vertical shaft member, so that the inclined rod can be deflected to make the lifting frame descend. The upper end of the water meter is squeezed by the pressing shaft member, and through the continuous movement of the vertical plate, the water meter can contact the conveyor belt assembly to realize the clamping of both sides of the water meter by the conveyor belt assembly and the vertical shaft member. When the pressing shaft member descends and contacts the water meter, the positions of the pressing shaft member, the lifting frame, and the inclined rod cannot be adjusted, which enables the sliding plate to apply pressure to the vertical shaft member to move and maintain the above stability. The vertical shaft member will generate a thrust on the sliding plate, which acts on the linkage component to increase the clamping force on the water meter.

[0014] Preferably, the pushing mechanism includes a second electric telescopic rod installed at the upper end of the lifting plate. The end of the piston rod of the second electric telescopic rod is fixed to one side of the lower end of the vertical plate, and the vertical plate is slidably installed at the upper end of the lifting plate.

[0015] Furthermore, through the action of the second electric telescopic rod, the vertical plate can be moved, that is, the positional relationship between the vertical plate and the conveyor belt assembly can be controlled. And when the vertical plate moves, it can drive the corresponding components to operate to realize the clamping and contact of the water meter, effectively limiting the position of the water meter.

[0016] Preferably, the pressure increasing mechanism includes a storage tank fixed to the upper end of the mounting plate. A sealing pressing plate is slidably installed in the storage tank. A first hydraulic cylinder assembly is fixed to one side of the storage tank. The end of the piston rod of the first hydraulic cylinder assembly is fixed to a fixing frame, and the lower end of the fixing frame is fixed to the upper end of the sealing pressing plate. The sealing pressing plate is hermetically installed in the storage tank.

[0017] Furthermore, through the action of the first hydraulic cylinder assembly, the fixing frame and the sealing pressing plate can be driven to lift. And the sealing pressing plate is hermetically installed in the storage tank, which can ensure the sealing effect and enable the water in the storage tank to be pressured and flow, continuously increasing the pressure.

[0018] Preferably, the moving mechanism includes a connecting groove opened at the upper end of the mounting plate. The connecting groove and the lifting plate are arranged in a staggered manner. Moving plates are slidably installed at both ends of the connecting groove. A conical sealing insertion pipe fitting is installed at the upper end of the moving plate. The two conical sealing insertion pipe fittings are located on both sides of the lifting plate. One side of the two conical sealing insertion pipe fittings is respectively fixed to two high-pressure corrugated pipe fittings. Second hydraulic cylinder assemblies are fixed to both sides of the upper end of the mounting plate. The end of the piston rod of the second hydraulic cylinder assembly is fixed to the moving plate.

[0019] Furthermore, the second hydraulic cylinder assembly can push the movable plate to move the conical sealing insert, so that the two conical sealing inserts can be inserted into the two ends of the water meter respectively, which is convenient for the flow of water and can ensure the sealing effect, avoid leakage, and effectively ensure the effect of high-pressure testing.

[0020] Preferably, the lifting mechanism comprises two telescopic rods penetrating the lifting plate, the lower ends of the telescopic rods are fixed to the upper end of the mounting plate, and the lower end of the lifting plate and the upper end of the mounting plate are rotatably connected to a first electric telescopic rod.

[0021] Furthermore, the extension and retraction of the first electric telescopic rod can push the lifting plate to move up and down in the axial direction of the telescopic rod, and can adjust the position of the water meter so that the water meter can be at the same height as the conical sealing insert, thereby ensuring the plug-in effect.

[0022] Preferably, a conveyor belt assembly is installed on the upper end of the lifting plate, and a plurality of conflicting shafts are rotatably sleeved on the upper end of the lifting plate from left to right in sequence, and the conflicting shafts conflict with the conveyor belt assembly.

[0023] Furthermore, the stability of one side of the conveyor belt assembly can be ensured by the effect of the interference shaft, so as to better interfere with the water meter and stably move the water meter.

[0024] Preferably, the conveyor belt assembly consists of a motor assembly, a conveyor belt and two support shafts, the two support shafts are rotatably sleeved on both sides of the lifting plate, and multiple interference shafts are located between the two support shafts. The conveyor belt is sleeved on the two support shafts, the motor assembly is fixed at the lower end of the lifting plate, and the motor assembly is fixedly connected to one of the support shafts.

[0025] Furthermore, the motor assembly can drive the support shaft to rotate, which can make the conveyor belt operate, and by controlling the rotation direction of the motor assembly, the position of the water meter can be adjusted, and the horizontal axis, vertical axis and pressure axis can all cooperate with the movement of the water meter. The friction shaft will conflict with the side of the conveyor belt close to the vertical plate, which can effectively ensure the stability of this side and facilitate the smooth movement of the water meter.

[0026] Preferably, the opposite sides of the two conical sealing insert pipes are both conical, and the conical sealing insert pipes are slidably mounted on the upper end of the moving plate.

[0027] Furthermore, it can adapt to water meters of various specifications and can fully ensure the effect of plugging with the water meters.

[0028] Preferably, a water changing component is installed on one side of the lower end of the storage tank.

[0029] Furthermore, it is convenient to add water and install corresponding valve components.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. Through the action of the second hydraulic cylinder assembly, the moving plate can be pushed to move the conical sealing insert fitting, facilitating the insertion of two conical sealing insert fittings into the two ends of the water meter respectively, facilitating the flow of water, and ensuring the sealing effect to avoid leakage, effectively guaranteeing the effect of high-pressure testing. At the same time, the conical sealing insert fitting can move relative to the moving plate, effectively adapting to water meters with improper adjustment, and better ensuring the insertion effect of the conical sealing insert fitting and the water inlet and outlet ends of the water meter. During actual production and preparation, a sealing gasket can be installed on the conical sealing insert fitting to improve the sealing effect and ensure the quality of detection;

[0032] 2. Through the action of the first hydraulic cylinder assembly, the fixed frame and the sealing pressing plate can be driven to rise and fall, and the sealing pressing plate is hermetically installed in the storage tank, which can ensure the sealing effect, enable the water in the storage tank to be pressured and flow into the water meter, continuously push the sealing pressing plate to descend, and can increase the pressure to monitor the pressure-bearing capacity of the water meter;

[0033] 3. Through the action of the second electric telescopic rod, the vertical plate can be moved, that is, the positional relationship between the vertical plate and the conveyor belt assembly can be controlled. And when the vertical plate moves, the corresponding components can be driven to operate to clamp and resist the water meter, effectively limiting the position of the water meter;

[0034] 4. When the vertical plate moves towards the conveyor belt assembly, the lifting frame can be effectively controlled to descend. And after resisting the water meter, the position of the lifting frame can be fully fixed, and the pressure on the lifting frame can be continuously increased to fully ensure the clamping force on the water meter. That is, during operation, as the vertical plate moves, through the action of the vertical shaft component, the position of the sliding plate can be fixed, so that the inclined rod can deflect, so as to make the lifting frame descend. The upper end of the water meter is squeezed by the pressing shaft component, and through the continuous movement of the vertical plate, the water meter can resist the conveyor belt assembly to realize the clamping of the two sides of the water meter by the conveyor belt assembly and the vertical shaft component. When the pressing shaft component descends and resists the water meter, the positions of the pressing shaft component, the lifting frame and the inclined rod cannot be adjusted, which can make the sliding plate press on the vertical shaft component to move to maintain the above stability. The vertical shaft component will generate a thrust on the sliding plate, which reacts on the linkage components to increase the clamping force on the water meter. Description of the Drawings

And through the continued movement of the vertical plate 9, the water meter can be made to contact the conveyor belt assembly 11 to achieve the conveyor belt assembly 11 and the vertical shaft member 14 clamping the two sides of the water meter. When the pressure shaft member 17 descends and contacts the water meter, the positions of the pressure shaft member 17, the lifting frame 22 and the inclined rod 21 cannot be adjusted, which can make the slide plate 20 press the vertical shaft member 14 to move to maintain the above stability.

The vertical shaft member 14 will generate a thrust on the sliding plate 20, which acts on the linkage component in the reverse direction to enhance the clamping force on the water meter;
